ABSTRACT:
A filter element has an internal coil spring which is magnetized to remove magnetizable particles from a stream of lubricating oil prior to the oil passing through an annular filter media. The annular filter media is part of a cylindrical filter element which includes an end cap that closes one end of the filter element and an internal sleeve which defines a hollow core. The filter element is disposed within a filter container having a cylindrical wall and a round end wall. The filter container is closed at one end by an end plate overlain by a cover plate. Lubricating oil to be filtered enters the container and accumulates in an annular space between the filter element and in an end space between the end cap of the filter element and the closed end of the housing prior to passing through the filter media. By being positioned in the end space, the coil spring exposes the lubricating oil to its magnetic field so as to remove magnetizable particles entrained in the oil from the oil and to retain those particles on the coil spring.
